Answer:
Step-by-step explanation:
<u>Given infinite geometric series</u>
- 1/4, 1/5, 4/25, 16/125, ...
<u>We see that</u>
<u>Sum of the series</u>
- S = a*1/(1 -r)
- S = 1/4*1/(1 - 4/5) = 1/4*1/(1/5) = 1/4*5 = 5/4

Step-by-step explanation:
we already have the first two as 26 and 28
third = a+5d
= 25+5
=30
Answer:
R + 5b = 300
Step-by-step explanation:
Rogers steps include a scale holding five bricks of equal weight and the scale reads 300 pounds.
We want to write an equation relating Rogers weight and the weight of the bricks to the total weight of the bricks to the total weight shown on the scale.
We have been told to use R for Rogers weight and b for the weight of a single brick.
Since Rogers is holding 5 bricks, the weight of 5 bricks will be 5b.
The sum of Rogers weight and the five bricks is equal to 300 pounds.
Therefore, the equation relating them is:
R + 5b = 300
